BUILDING BLOCK OR SLAB.

Application filed September 11, 1922.- Serial No. 587,551.

' building blocks or slabs, and more partic- .ul-arly iii building'blocks or slabs which are in the form of an irregular H and are adapted to be composed into hollow insulating walls. ln order to produce with building blocks of this type a good joint between adjacent blocks when laying the same into a wall it has been proposed to construct the side portions thereof with equal lengths but offset from each other, one side portion at each end of the block projecting beyond the other one. The object of the improvements is to produce a block of. the class referred to which can be laid with a proper joint also at the corners of the'wall, and l attain `this object by constructing the side portions and the web portion of the block with specie relative dimensions, such as will be explained hereinafter.

ln order that my invention be more clearly understood an example embodying the same has been shown in the accompanying drawing, in which the same reference characters have been used in all the views to indicate corresponding parts. ln said drawing,

liig. l, is a plan view showing the building block'or slab,

Figs. 2 to 6, are similar plan views showing forms of the block lderived from the basic term shown in vFig. 1,

Figs. 7 and 8, are respectively an eleva-` tion and a vertical section showing a part of a wall made from my improved block,

Figs. 9 and 10, are plan views showing two superposed courses of blocks or rslabs laid in a wall, and

Figs. 11 and 12, are similar plan views showing a modification.

As appears from Fig. 1 the building block consists of a web portion a and side ortions marked as a whole ci and all. he side portions are equal in length, but theyY are odset with relation to each other, the length of the part '52 in eab side portion being largervthan that of the part b. lnl ablocir constructed according to my invention the web portion a is square in plan view and the length of its sides .is equal to the thickness of the side portions d and d1, which thickness is one third of the length of the sideportions d and d1.' .parts o of the side portions, which are located at opposite sides of the ,web portion a have a length equal to one sixth of the total length c of the side portions CZ and d, and

the length of the long parts b2 is equal to 55 one half of the'length c. The mid-parts b of the side portions have the length i c, and they have the same dimension as the web portion a. Therefore the total breadth of the block, which is the sum of the lengths il@ of the parts Z7, a, and b, is equal to c.

In Fig. 1 l have shown dotted lines indi eating how other forms of blocks are derived from the basic form, which 'forms have been shown in detail in Figs. 2 to 6. F5

In the example shown in'Fig. 2 the projecting parts of the side portions located at one side of the web portion have been omitted. ln the modification shown in Fig.

3 at one side of the web portion the short t@ part o of one of the side portions is omitted and the length of the long part is reduced by c the remainder having the length of the part b- In the example shown in Fig.

i the' long part b2 of the side portion 1s $5 cut od' at one side of the web portion a. F ig. 5 shows an example in which the long and the short parts b and b2 ot one side portion and the long part of the other side portion have been omitted, and in- Fig. 6 9@ only the web portion a of the block is omitted so that in tact the block consists of two sectional blocks each having the length c and the thickness o.

lnFigs. 7 to 8 l have shown a wall built to from my improved blocks. As appears more particularly from Figs. 9 and 10 consecutive courses of blocks are disposed so as to break joint throughout the side por tions, and the web portions are placed one above the other so as to provide hollow insulating spaces. The course on which the beams e are supported is built from sectional blocks of the form shown in Fig. 6, which blocks cover lthe hollow spaces. dow sill is built from blocks of the form shown in 5, and the vault of the window is made from blocks of the form shown in Fig. 2.

ln Figs. 11 and 12 have shown two 110 courses showing a modification of the joints at the corner. By using sectional blocks The short 60 rlhe winof the form shown in Fig. 6 the blocks cen be laid so as to breek jointet the corner.

I claim: 1. A building block consisting of e web portion and `parallel sideportions, the side portions each having a. length equal to three times the length of said web portion end each side portion projecting one half its length at one side of said web portion enel one sixth its length at the opposite side thereof, the shorter and longer projections of said side portions being on the same side of said weh.

2. A building block consisting of a. Web portion and parallel side portions, sai-icl pormeente tions having the same thickness and seid webv portion being e cube, seid. side portions eech having e, length equal to three times the length of said' web portion and each side portion projecting one heli its lengthen 2o
